Validation of the 8th edition of the AJCC/UICC TNM staging system for tongue squamous cell carcinoma

ConclusionsThe classification on T3 in the 8th edition can be seen as reasonable with regard to prognosis. Nodal metastasis was significantly correlated with T classification and DOI; however, the probability of subsequent nodal metastasis in patients with T2N0 was almost same for the criteria in the 7th and 8th editions, therefore, the same careful management as before is required for patients with N0 disease.
